Locale value for folders must be taken from properties not from the node name

Locales for the cms are defined at /hippo:configuration/hippo:frontend/cms/cms-services/localeProviderService. For example by a childnode with two properties country and language. If you set them to "gb" and "en" you would expect that the hippotranslation:locale property on a folder or document for this locale becomes "en_GB". Which is the result of the Locale#toString method.

Instead, the name of the configuration node for the locale is used. So if that node has the name "english", that will be the value of the hippotranslation:locale property.
